One spawns along the southern edge, including the location shown in the 1st map.

If you don't want to fight through mobs to get to the first raven, the other is on the inaccessible plateau of a hill close to the portal from Dalada Uplands (2nd map). If you are patient (and find a good spot), the bird will wander within range of Charm Animal; once cast, you will still be able to charm the raven even if it moves farther away.
